TECHNICAL PASSPORT INSTALLATION and OPERATION MANUAL
When the boiler is connected to a heating system,
it is mandatory to install a 3 bar relief valve and
expansion vessel. No shut-off fittings may be installed
between the relief valve, expansion vessel and boiler.
*
It is mandatory to install a three-way
valve (Laddomat or similar) or a four-way
mixing valve which to ensure that the
temperature of the heating medium fed
into the boiler from the heating installation
is at least 65°С.
Table 5. TROUBLE-SHOOTING TABLE
Cause Solution
Installation damage
1. Due to unsealed connections
1. Install the connecting piping strain-free to the boiler
connections. Connect the heating installation outlet to
connection B. Connect the heating installation inlet to
connection A. Mount the cock Y included in the set.
2. Due to accumulation of deposits.
Condensate and tar formation may reduce
the performance and life of the heating boiler.
The temperature at the boiler inlet must not
be less than 65°C, boiler water temperature
at the outlet must be between 80°C and 85°C.
2. It is mandatory to install a three-way thermostatic valve
which will prevent the temperature dropping under 65°C at
the inlet.
- In order to increase the operational life of the boiler it is
recommended to install a buffer vessel with capacity of 55 l
per 1 kW of installed power.
3. Due to freezing
3. If the heating installation, including the piping network,
has not been built frost-proof, we recommend that you fill
the heating installation with a liquid which has low freezing
point and corrosion protection and antifreeze agent.
Output too low
1. Insufficient draught
1. Check chimney condition and measure draught. (must be
performed by an authorized service)
2. Heating value of the fuel is too low.
2. If the heating installation, including the piping network,
has not been built frost-proof, we recommend that you fill
the heating installation with a liquid which has low freezing
point and corrosion protection and antifreeze agent.
3. Presence of soot deposits and/or tar on
the flue damper in the upper chamber which
prevent its tight closure.
3. Clean the flue damper and make sure that when moving
its closing/opening lever it provides adequate sealing of the
flue gas outlet in the upper chamber. (must be performed by
an authorized service)
4. Presence of soot deposits and/or tar in the
flue pipes in water jacket in the back of the
boiler
4. Clean the heat exchange surface of the flue pipes using
the brush from the cleaning tools set. After the cleaning is
completed, remove any soot through the inspection opening
in the back of the boiler. Must be performed by an authorized
service.
Boiler water too hot, heating bodies too cold
1. Hydraulic resistance is too high.
2. Air in the system
3. Inoperable circulation pump
Make sure the circulation pump has been properly selected
and the heating installation is of the proper dimensions. (You
must contact your installer.)

*
Such connections must be performed by
a technician / service shop authorized for
such operations.
